SURGICALJNSTRUMENT FOR AMPUTATION OF THE RECTUM.

Specification of Letters Patent. Application filed March 24, 1906. Serial No. 307,794.

Patented Oct, 23, 1906.

To all whom it may concern.-

Be it known that 1, CHARLES G. GRUM- RI NE, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Surgical Instruments for Amputation of the Rectum, of which the following is a specification, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object a novel surgical instrument for amputation of the rectum; and it consists of thecombination of devices and appliances hereinafter described tion.

andclaimed, andillustrated in the accompanying drawings, in which Figure l is a view in elevation. Fig. 2 is a view in section on the line 2 2, Fig. 1, showing the features of the device in normal posi- Fig. 3 is a view, partly in section and partly in elevation, showing features of the device in operative position, the tenacula being extended. Fig. 4 is a cross-section on the line 4 4, Fig. 3.

My improved instrument is especially adapted and intended for use in cases of prolapsus ani and hemorrhoids.

The construction of the instrument is as follows, the same consisting, essentially, of an elongated shellfla, the same having, preferably, a removable cap I): Secured within the shell in any suitable manner are a series of spring-arms (indicated at 0) converging toward one end of the shell, as shown in the drawings, and at their converging ends provided with corresponding tenacula,- (indicated at (1,) the tenacula being arranged to be projected outward through the shell a, asindicated in the drawings, the shell being formed with suitable openings e, through which the tenacula may project. Normally the tenacula are withdrawn into the interior of the shell. In active operation they are to be advanced through the shell. The springarms 0 will normally retract the tenacula within the shell when the arms are free to exert their normal tension. Said arms maybe secured within the shell in any suitable manner. As shown, the shell is provided with an interior ring or collar f, to which the adjacent ends of the arms are secured, as by rivets g. To more effectually guide the tenacula in their advancement and retraction, I prefer also to provide the interior of the shell with a perforated collar ,(indicated at h.) To force the tenacula outward, Ihave shown a movable head (indicated atc') threaded, as indicated at 3', upon a stem is, provided with a milled head Z, the stem 7c being rotatable in a sleeve m, connected with the shell 0.. To prevent the reciprocation of the stem it, I have shown the same constructed with an annular recess, (indicated at 11,) into which projects a pin 19.

It will readily be observed that by turning the stem 7c the head i will be advanced and retracted. The one movement expanding the converging extremities of the. springarms 0 to project. the tenacula through the shell, the opposite movement of the stem moving the head i to permit the spring ten sion of the arms 0 to withdraw the tenaculawithin the shell of the cartridge.

is also preferably constructed on its exterior periphery at the end thereof adjacent to the perforations c with a series of recesses-(indicated at g) to more readily permit the use of the needle in the completion of the surgical operation, as hereinafter described.

Having explained the construction ofthe instrument, its use in performing an operation will be understood.

When the patient is to be operated upon,

the rectum is dilated and prepared in a manner well known to the surgical profession, the

prolapsed portions being replaced. Suitturning the stem is in the proper direction the tenacula are forced outward into the external' sphincter which holds it in place. The shell is of a size lar e enough to dilate the rectum and force the b ood out of the rectum into the bowel, leaving the diseased portion to be amputated pale and bloodless. The amputation is then made, using the shoulder of the shell as a guide in making the amputation. When this has been accomplished, the gut is picked up, and with suitable tissue-forceps and a small. curved needle a continuous suture is put in, after which the rectum is laced as requirred. The needle, it will be understood, is guided in its operation by the recess g in the periphery of the shoulder of the The shellshell. The amputation being completed, now turning the stem is in the proper direction the tenacula are withdrawn into the shell, the shell withdrawn, and the wound properly dressed. The head i is preferably provided with a plate 8, having fingers t projecting outward between the spring-arms c, to prevent the head from turning.

What I claim as my invention is 1. Inv a surgical instrument the combination of a shell, tenacula located within the shell toward one extremity thereof to be advanced therethrough and withdrawn thereinto, and: means toact'uate the tenacula.

2. In a surgical instrument the combination of a shell, spring-arms secured therewithin provided at one extremity thereof with tenacula to project through the shell, and means to advance the tenacula through the shell, the tension of the spring-arms normally retracting the tenacula within the'shell.

3. In a surgical instrument the combination of a shell, spring-arms secured therewithin converging toward one extremity thereof and provided at their converging ends with tenacula to project through the shell, and means to advance the tenacula through the shell, the tension of the spring-arms normally retracting the tenacula within the shell.

4. In a surgical instrument the combina tion of a shell, a collar located within the shell toward one end thereof, spring-arms secured at one extremity thereof to said collar, and provided at their opposite extremities with tenacula to project through the shell, and means to advance the tenacula through the shell, the tension of the spring-arms nor mally retracting the tenacula within the shell.

5. In a surgical instrument the combination of a shell, spring-arms secured at one extremity within the shell and-provided at their opposite extremities with tenacula to project through the shell, a perforated ring or collar within the shell to guide the movement of the tenacula,and means to advance the tenacula through the shell, the tension of the springarms normally retracting the tenacula within the shell.

6. In a surgical instrument the combination of a shell provided with a shoulder at one extremity of the shell, tenacula located within the shell toward the shouldered extremity of the shell to be advanced through the shell and withdrawn thereinto, and means to actuate the tenacula.

7. In a surgical instrument the combination of a shell provided with a shoulder at one extremity of the shell, tenacula located within the shell toward the shouldered extremity of the shell to be advanced through the shell and withdrawn thereinto and means to actuate the tenacula, said shoulder ofthe shell provided with a series of recesses upon its periphery.

8. In a surgical instrument the combination of a shell, spring-arms secured therewithin and converging toward one extremity thereof and provided at their con-verging ends with tenacula to project through the shell, a movable head within the converging ends of the arms to advance the tenacula through the shell, and means to advance and retract said head, the tension of the spring-arms normally retracting the tenacula within the shell.

9-. In a surgical instrument the combination of a shell, spring-arms secured therewith in and converging toward one extremity thereof and provided at their converging ends with tenacula to project through the shell, a movable head within the converging ends of the arms to advance the tenacula through the shell, a rotatable stem having a threaded engagement with said head to advance and retract the head, said shell provided with a sleeve through which said stem projects.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
